To allwhom 'it may concern:

Be it known that lwe, EMoRY J GODMAN and VILLIAM H. NIEMEYER, both of the city of Baltimore and State of Maryland, have 5 invented certain Improvements in Machines for Sealing- Bottles, of which the following is a specification.`` 1

This invention consists principally in the incorporation in a machine for the'above 1C described purpose, of appliances' whereby after a predetermined and sufiicient pressure has been applied to asealing cap on a bottle to effect- 'a tightclosure, the saidpressure .is

maintained substantially without increaseo' decrease throughout the entire sealing operation, and without respect to any deviationv in height (within a reasonable limit) of the bottle from what might be termed the lstandvard size. In' other words, by means of the improved mechanism as applied to a machine for sealing bottles, changes in lsize or shape of the bottle -head, or in the height of the bottle within a reasonable limit,'has no effect whatever to disturb a predetermined pressure which is applied to the sealing cap at the beginning of the sealing operation,

and maintained without change until the sealed bottle is releasedfrom the sealing dev1ces.-

33- In the further description of the said invention which follows, reference is made to the accompanying drawings forming a part hereof, and in -which,-

` Figure 1 is a partly sectional side .view of 35 the improved machine.- Fig. 2 is. an enlarged central vertical section of the upper portion of the same..v Fi 3 is av section of Fig. 2 taken onthe dotte line arr-w. Fig. 4

is a Isection of Fig. 2 taken 'on the dotted 4'? line y-y`- Fig. Y5.is a still further enlarged ,section -of Fig. 2 taken on the dotted line To the upper end ofthe bar- 3 is secured the 9 which unites theA Voperation hereinafter described.

sealing head which consists of a cylilider 10 having a bracket b whereby it is connected to the bar 3, and a hollow lug c the ,si/des of eration hereinafter described. 'The lower portion of the cylinder 10 for a limited distance beginning at the mouthpiece, is enlarged in internal diameter, and into this enlargement is loosely placed the cylindrical fblock 15 which rests on an annular shoulder formed on the mouth-piece; and between the block 15 and the underside of'the'screw plug 12, is confined -a stiff coiled spring 16 which 75 is' under compression. vWith this construction, should sufficient u ward pressure be applied to the cylindrica block 15 it can be raised until its upper surface comes intocontact with the shoulder e formed'by enlarging. 8o the bore ofthe cylinder'lO as before described. The cylindrical block 15 for a limited vertical distance beginning' at its bottom, is conically bored and fitted with a correspondingly shaped annular capping tool 17 formed preferably of hardened steel; and abov'ethis tool, the block is provided with a'cylindrical hole f.

19 is a cap-holding spindle whose lower end passes looselyV through thp hole inthe cylindrical block'l, and extends to nearthe bottom of the capping tool 17 and the said, spindleis supported -in this position? by a s v collar formed thereon', whichrests on. the

top of the cylindrical block; The upper end 95 of the spindle '19 is centraliaedby-the screw plug 12in which it lits loosely.

20 is a compressed spiral spring\vhich is confined endwisebetween the screw plug 12 and thev collar g; and its oiice is. to v1e1d' 100l ingly hold the sealing cap von the bottlehead,

at and prior tothe beginning of the sealing 22 is the sealing cap hol-der consisting of a rin formed insegments which are backed 1-05- by p atrsprings h as best lshown in Fig.- 5.

This device is placed between an. inwardlyojectng lip i 1n the mouth-piece 13 and tliej'.-l v

ower surface or edge ofthe cappingxftool 17;,'and is free -to expand andcontractas' re. 1 10 jab The' upper `engl Qfthes'prlng' 29. bears against the bottle Supporting appliances'.

in the cont-inked movementv ofthe sealing head, the crown ofthe sealing' 'cap with its joint -forming (gasket is compressed between the bottle hea and the lower end ofthe spring'- backed spindle 19 suiliciently to produce a tight joint:- At this time the bottle 4'is stationary, and in a further downward motion of the Sealing head, the capping tool 'is forced over'thesealing cap, and the same bgolht tightly against the bottle which is' Vseal sealing head continues itsdownward course when the capping tool stops.

In the cpnstruction of theseallng'head as l sealing operation performed asdescribed.

i' above described, ,the mouth-piece 113,y is subjected tothe combined vdownward force of thesoiled `springs 16 and 20, and should a A'bottle be crushed in.; .the sealingoperation whenl the cylindrical block 15 is in its'highest position with respect tothe cylinder 10 0I" thefsealing head, the sudden extension of the springs, would cause the cylindrical blockto strike the mouth-piece after the manner of a hammer, ,whlchmightproduce the dlslocation of or injury to that device. This danger is entirely obviated i in theconstruction shown in Fig. 6 in'which an odset vertically moving ring 45 supported by apro- -jection r in the cylinder 10, yreceives the pressure of the two spiral springs, the cylindrical block bearingv onthe mouth-piece with a force l diie to its weight only.
